Laszlo Agocs 7ed6a247bf Fix synthesizing mouse events when touches change ordering
There is no guarantee the touches will be listed in the same order in
an update: the platform/generic plug-in, the drivers, etc. are all
free to shuffle the list of touch points in each report (even though
the order is fairly stable with most systems).

Therefore, to be safe, move and release events should be generated not
from the first point in the list but from the one with the matching
id.
